Digital inputs functions
Function
Each digital input chosen by pressing >left< or >right< will be assigned to a
certain function as long as the regulator function is active.
Select from:
-
„inactive“
(The digital input has no function.)
-
DI1 „torque switch“
(the torque switch for the closed condition is connect-
ed to the selected digital input.)
-
DI2 „switch CLOSE“
(the slide end switch for closed condition is routed to
the selected digital input.)
-
DI3 „switch OPEN“
(he slide end switch for open condition is wired to the
selected digital input.)
-
DI4 „control v-measure“
(he digital input is used to block/release the
measurement using an external signal such as flood messages or limit val-
ues for measurement start or similar. Indicated as: 0 l/s, inputs and outputs
set will de-energise)
Logic
Toggle between inverse and non-inverse input by pressing >up< or >down<
arrow keys. This means that e.g. slide valve signals can be configured as be-
ing normally closed and cable breaks can be detected without any problem.
The default setting is „non-inverse“.
Name
The name of a digital input can have up to 3 characters. These names will be
indicated in the main screen and in overview menu; see overview menu. Set
the names as described in chapter 9.4.1.
Please observe that the digital inputs are passive and therefore shall be sup-
plied by an external 24 V DC power supply!
The signal current is 10 mA. Please ensure reliable conductivity by using relay
or end switch contacts made of high quality material.
